Description

TECHNICAL FIELD The present invention relates to a fishing line made of ultra-high molecular weight polyolefin filament fiber and a method for producing the same. More specifically, the present invention relates to a lightweight and high-strength fishing line suitable for fishing of sweetfish, hellebuna, and the like, and a manufacturing method thereof.

[Prior Art] There are many types of fishing line such as a reel line, a river line, a Harris line, and an Otori line which are wound up on a reel. These fishing lines are generally required to have characteristics such as light weight and high strength.

By the way, many conventional fishing lines use monofilament-shaped fibers generally called Tegus. This is because it is easy to manufacture while at the same time taking advantage of the property that it is difficult to get entangled and the property that it can be easily rolled up. And, because it has no curling habit, good touch, durability, etc., conventionally, nylon 6,6,6-nylon, 6,1
Fiber materials such as 0-nylon, polyester, vinylon, polyvinylidene fluoride and metal fibers have been used.
Further, as proposed in JP-A-60-164421, a monofilament fishing line for fishing reels made of high molecular weight polyolefin is also known.

[Problems to be Solved by the Invention] However, even if the monofilament-like yarn made of a high-molecular-weight polyolefin proposed in Japanese Patent Laid-Open No. 60-164421 is applied to a fishing line for away such as sweetfish and hebruna. However, there is a problem that the thread is too thick to be applied as it is. That is, the fishing line for the line thread or the needle thread such as the sweetfish and the helluna needs to be much lighter than the fishing line of the known example. And the above-mentioned JP-A-60-16442
If the publication No. 1 is simply made thin, it has a monofilament-like shape, so that it tends to have a twisting tendency and has a problem that it is difficult to operate because of high modulus (rigidity).

Especially in ayu fishing, as is well known, there is a fishing method called friend fishing, in which a live ayu is tied with a nose ring, released into the water, made into a decoy (bait), and another ayu is attracted and hooked for fishing. . In this case, the most important thing is to create a condition in which the decoy sweetfish can swim freely and lively for a long time in a natural state. For this purpose, the fishing line must be thin and light.

From such a background, in nylon, a very thin thread such as 0.2 to 0.4 (thread diameter 74 to 104 μm) is mainly used. However, even a fishing line of this thickness was far from being able to move about freely because of the resistance of the line in the water to the decoy.

Further, a fishing line made of polyvinylidene fluoride is in a similar state.

In addition, recently, tungsten and amorphous metal fibers have been proposed, which enables thinner fishing lines.
There is also a proposal to improve the decoy movement by using No. 0.175 (49 to 69 μm) yarn. However, the metal fiber has a drawback that it is heavy, for example, the weight of the fishing line of the metal fiber of 0.08 is 0.0272 g / m,
This is a value of about 10 times that of nylon. Therefore, it is hard to say that the improvement of decoy movement is sufficient.

In order to solve the above-mentioned problems of the prior art, it is an object of the present invention to provide a fishing line that is lightweight, has high strength, is less likely to have a twisting tendency, and is easy to operate as a fishing line, and a manufacturing method thereof. More specifically, it is an object of the present invention to provide a fishing line for ayu or hebruna which has a fineness comparable to metal fibers and a light weight equivalent to that of nylon while maintaining high tensile strength.

[Means for Solving the Problems] In order to achieve the above object, the method for producing a fishing line of the present invention comprises:
A method for producing a fishing line composed of ultra-high molecular weight polyolefin filament fibers, which comprises first separating multifilament fibers into monofilament fibers, and then preparing a plurality of the monofilament fibers so that the total denier is 100 denier or less. It is characterized in that it is formed into a string-like fishing line by assembling or twisting.

In the above structure, it is preferable to kink by heating or applying a resin during or after the step of assembling or applying the twist.

Further, in the above-mentioned structure, it is preferable to apply a dye-added resin or a resin to which no dye is added to the surface of the string-shaped fiber after forming the string-like shape.

Further, in the above-mentioned configuration, it is preferable that the number of pitches for assembling the string-shaped fishing line is 200 to 2000 P / m, or the number of twists for twisting is 100 to 1000 T / m.

[Operation] First, the operation of the fishing line obtained by the above-described manufacturing method of the present invention will be described.

Since the fishing line of the present invention is made of an ultra high molecular weight polyolefin filament fiber having a total denier of 100 denier or less, it has a strength of 20 g / denier or more, preferably 30 g / denier or more, and thus is a lightweight and high-strength fishing line. be able to. Next, since the fishing line is composed of multifilament fibers and is assembled or twisted into a string shape, it is possible to obtain a fishing line which is hard to be twisted and easy to operate as a fishing line. In other words, the monofilament shape (Tegus shape) has a high modulus (rigidity), so it is difficult to tie it like a tennis gut,
There is a problem that the loop becomes large and a twisting tendency easily occurs, and it is difficult to remove once the twisting tendency occurs, but the above-mentioned problems are caused by constituting the single yarn with thin multifilament fiber and assembling it into a string or twisting it up. Can be improved.

In the above description, the ultrahigh molecular weight polyolefin filament fiber is made of, for example, ultrahigh molecular weight polyethylene fiber or ultrahigh molecular weight polypropylene fiber, has an average molecular weight of 200,000 or more, and is generally called gel fiber. This fiber can be obtained by a method such as gel spinning / drawing, melt orientation drawing, and solvent swelling drawing.

In the above, the total denier is preferably 70 denier or less, and particularly preferably 50 denier or less. The preferred number of multifilament fibers is 2 to 5.

In the above, denier means the weight per 9000 m of fiber length (unit: gram).

Further, in the above description, the fishing line of the present invention has a number of pitches for assembling the string-shaped fishing line in the range of 200 to 2000 P / m,
Alternatively, it is preferable that the number of twists in the twisting is in the range of 100 to 1000 T / m, and further, the number of pitches for assembling the string-like fishing line is in the range of 400 to 800 P / m, or the number of twists in the twisting is The range of 200 to 700 T / m is more preferable. The reason for this is to impart appropriate rigidity and suppleness, and also to make it difficult to be crushed when rubbed in a rocky place, and to impart a characteristic that is easy to operate as a fishing line.

If the number of assembled pitches or the number of twists is less than the above range, the convergence of the plurality of filaments is not sufficient, the appearance is not good, and the fishing line is likely to come apart during fishing, and one filament is damaged. The stress is concentrated there and the overall strength is reduced, which is not preferable. Further, if the number of assembled pitches or the number of twists exceeds the above range, the tensile strength and the knot strength tend to be extremely reduced, which is not preferable.

Further, in the above, it is preferable that the surface of the filament fiber is coated with a resin or a colored resin. This is because the resin allows the multifilaments to be integrated and well integrated. Further, the coloring resin is applied, for example, if it is colored in a fluorescent lemon color, it becomes easy to attach and detach the ayu to the nose ring, and it becomes easy to attach the inverted needle or hit the inverted needle. . Furthermore, there is an advantage that the state of the fishing line in water can be easily identified.

Next, the operation of the structure of the method for manufacturing a fishing line of the present invention described above will be described.

In the method of the present invention, first, multifilament fibers are divided into monofilament fibers. The reason for separating the fibers is that it is difficult in the manufacturing process to obtain a multifilament fiber having a total denier of 100 denier or less by spinning and drawing.
By separating the fibers and leaving a proper kink and twisting habit, when the rope is assembled or twisted in a later process to form a string, friction and catching between single threads are increased, and fishing line with high integrity is obtained. This is because

Next, a plurality of separated monofilament fibers are prepared so that the total denier is 100 denier or less, and these are assembled or twisted to form a string, which is used as a fishing line.
The reason why the total denier is 100 denier or less is that the fishing line is lightweight and has high strength as described above.
In addition, it is composed of multifilament fiber and assembled or twisted into a string shape gives appropriate rigidity and flexibility, and also provides the property that it is hard to be crushed when rubbed in a rocky place and is easy to operate as a fishing line. This is because. At this time, as described above, the number of pitches for assembling the string-shaped fishing line is set in the range of 200 to 2000 P / m,
Alternatively, it is preferable that the number of twists in the twist is in the range of 100 to 1000 T / m, further, the number of pitches in the assembling is in the range of 400 to 800 P / m, or the number of twists in the twist is 200 to 700 T / m. It is more preferable to set to the range.

In the method of the present invention, a kink stopping treatment is performed by heating or applying a resin during or after the step of assembling or applying twist. By these treatments, it is possible to improve the morphological stability of the fishing line and prevent the thread from breaking down and becoming less strong even when it is rubbed or twisted during fishing.

In the above, the heating temperature is preferably 60 to 90 ° C., and the strength may decrease on the high temperature side, and caution is required.
The resin used for the resin processing is selected from polyurethane, epoxy resin, acrylic resin, polyvinyl acetate resin, etc. At this time, coloring can be performed by mixing a pigment or a dye such as a dye in the resin solution. In particular, mixing a dye with a resin is important for coloring because the ultrahigh molecular weight polyolefin filament fiber used in the present invention cannot be dyed by an ordinary method.
